Civilization 4 Demo

I have just been playing the Civilisation 4 Demo and I am impressed. The tutorial has a talking head of Sid himself taking you through the basics of the game (has his voice too), but the one thing that has annoyed me more than anything about the previous games is that they have required an excessive level of mouse clicking to conduct the simplest of tasks and Civ4 seems to have eliminated most of that. Plus the game seems less complex from an interface standpoint. And that inturn should make later stages of big games much more enjoyable.
